What a Water Supply Means 
to a Community 

AN adequate supply of clear, pure water is absolutely 
XX necessary to a modern progressive community 
today. It is the most important public utility that 
a town can possess, because upon it rests the health and 
prosperity of all the inhabitants. There 

A 

must be sufficient water for domestic and , r .^ , 

Vital 
industrial needs, and also for fire protection, Necessity 

if the people are to live in comfort and safety. 

A properly built waterworks system guarantees to each 
individual in the community comfort, health and depend- 
able protection against fire, while an insufficient supply 
endangers life and property, and causes great inconven- 
ience to everyone. No community can excuse a poor 
waterworks system on the plea that it cannot afford the 
necessary improvements. Improving an unsatisfactory 
waterworks will more than repay the cost of the work 

within a very short time. In any community ^ 

, - , Economy 

where the water system is modern and ade- 
quate for the needs of the people, fire insurance rates are 
low, the value of property high, and the town a comfort- 
able and attractive place in which to live and work. 
People seek out such a community for a home. Industries 
will come to a town which offers to safeguard the health 
of their employees as well as to supply fire protection and 
plenty of good water for their factories. The progressive 
community of today realizes that a modern waterworks 
system is its greatest single asset.

Advantages of the Gravity Pressure 
Water System 

TF an ample supply of pure water is available at a proper eleva- 
-*- tion, and not too far distant from the town, the design of the 
waterworks system becomes simple ; the water will flow through an 
impounding reservoir or directly into the distribution system with- 
vj f * out tn e aid of machinery, under the force of gravity. 

yy Such ideal conditions are, however, very seldom 

available. Usually a pumping station is necessary 
to lift the water from a well or other source of supply to an elevated 

tank or reservoir. When the water is 
thus stored, it is available for immediate 
use under pressure. This arrangement, 
with the usual distributing pipes, valves, 
and hydrants, is known as a gravity 
pressure waterworks system. 

If the water is not clear or pure, a 
filter plant is also necessary to purify 
the supply before it is pumped into the 
elevated tank or other storage. 

Pumping water directly into the dis- 
tributing system for domestic use and 
fire service without the use of an elevated 
tank or reservoir known as a direct 
EI ' : ta ">k. pressure system is, in most cases, 

unsatisfactory and inefficient. The quantity and pressure of the 




More Effi- 



water depend entirely upon the operation of the 



pump which, therefore, must be sufficiently large and 
cient than & 

Dire r powerful to handle the maximum requirements. 

p Naturally, the pump cannot always respond at once 

to every unusual demand, and the pressure, instead of 
being uniform, fluctuates throughout the system. When, as frequent- 
ly occurs in such a system, the flow of water is suddenly reduced and 



P I T T S B ( K G II - I) K - MOINES 5 T E EL COMPANY 



as suddenly increased, the machinery, water mains and service pipes 
are subjected to heavy strains by water hammer, which ni 

<>us damage. 

If the water is stored at an elevation, as m an el< teel 

tank, it is always available for immediate use- at uniform pressure, 
and the community is not directly dependent upon the successful 
- ration of machinery for its supply. 

Pumping into an elevated tank is also more econofl 
"direct pumping", because the pump always works under a uniform 
load and at maximum capacity. With an elevated tank, pumping 
is usually not required during the entire twenty loin hoUJ 

of power and supervision is greatly reduced Where ( I 
power is available, automatic remote controls lor the pumps are 
usually installed which operate as follows: when the water m the 
tank falls to a predetermined level a pressure regn. 
ed control device mounted on the tank operates an 
nit c una* : ic switch in the pump house, start ing 

the pumps, and stopping them when the tank is full This 
ment can be adapted to practically all conditions, even though the 
pump house and water tower are located several miles apart. With 
fuch an installation only occasional visits to the pump house for 
oiling and inspection are necessary. Necessary repairs may be made 
while the pump is idle so that duplicate pumping units are unnc 

A large tank and a small pump are better than a small tank and 
a large pump, because their operation is safer and more economical. 

The strongest argument in favor of the gravity pressure system 
s absolute dependability for fire protection. How often have 
vou read of or seen a disastrous conflagration which 
got beyond control because, at a critical time, the p. 

wells, pumps, or power failed? The demands upon ^ 
some part of the system proved too great just when 
water was most needed. Such a disaster is practically impossible 
with a properly designed gravity system, for the force of the water 
stream is always dependable. For reliable fire protection, a gravity 
pressure system is by far the safest and most reliable.

Elevated Steel Water Tanks 
for Municipal Service 

A Pittsburgh-Des Moines elevated steel water tank is the efficient 
^ ■*• and economical water storage system for industrial and 
domestic use and for fire protection. In the average town of approx- 
imately ten thousand population, the elevated steel tank is almost 
Efficient invariably a part of the modern waterworks system. 
and Eco- * n t * ie larger C1 ^ 1GS also » water towers are being used 
nomical extensively as auxiliary units of the main water 
system to provide efficient fire protection for out- 
lying or isolated districts, and for carrying "peak loads" of water 
consumption. 

A standard Pittsburgh-Des Moines elevated steel water tank 
consists of an all-steel tank with a hemispherical bottom supported 
upon a steel tower, the whole being constructed as a single unit. 
The tower consists of four or more sloping steel columns, their bases 
Tower securely anchored to concrete foundation piers. The 

Design number of columns varies with the size of the tank, 

as many as twelve being used for very large capaci- 
ties. The tower is wind-braced by steel struts and rods, and at its 
juncture with the tank is usually reinforced by a horizontal, circular 
steel girder, with a railing, which is called the balcony. The tank 
is provided with a steel roof to prevent contamination from outside 
sources and to maintain a uniform temperature of the water. When 
the elevation of the tank is not more than three times its diameter, 
the columns may be vertical instead of sloping, in which case the 
balcony is usually not required. In all of these structures the stres- 
ses are scientifically calculated to determine the size of members 
and the thickness of plates which must be used to give the structure 
a wide margin of safety. Proper ladders are supplied to provide 
easy access to all parts of the structure. 

A standard Pittsburgh-Des Moines tank has a hemispherical 
bottom; this shape has smaller and more easily calculated stresses

than any other flat or curved surface. It is self clean- 
ing and also very economical in weight of metal and 
cost of manufacture. When required, we can supply 
conispherical, elliptical or other shapes of bottoms having complex 
curves, but our standard hemispherical type is most generally used. 
The tank is usually connected to the water mains by a single 
vertical riser pipe, protected by a wooden frost case which has the 

proper number of air spaces to protect the water 
Riser 

against freezing. Sometimes all-steel riveted riser 

Pipe 

pipes of large diameters are used, without frost cases; 
the large diameter effectively prevents the water freezing at the 
center of the pipe. This large riser acts as a catch basin for any 
sediment in the water and can be quickly cleaned at any time by 
means of a blow-off valve connected to the sewer, without inter- 
rupting the service. The steel riser is provided with a manhead, 
allowing convenient access for inspection and painting. 

These elevated tanks may be constructed with capacities ranging 

from 1,000 to more than 1,000,000 gallons, and with 
Heights 

heights up to 300 feet. For municipal service the 

Caoacities usual opacities are from 30,000 to 500,000 gallons 
with elevations of 75 to 1 50 feet. A list of Pittsburgh - 
Des Moines standard tanks will be found on page 39. 

Wood tanks on steel towers can be replaced with steel tanks, 
as shown in the illustration of the Lohrville tank and tower

upon to replace wood tanks on masonry tow

an illustration of the success with which this can 
1 be done. In practically every instance it will be 
1 more economical to replace with a steel tank than to repair 
the old wood tank or replace it with a new wood tank. Steel 
tanks cost but little more than wood and last indefinitely, while 
wood tanks must be repaired at frequent intervals and usually must 
be entirely replaced after ten or twelve years.

A Complete Waterworks Service 
for the Municipality 

T\ /TANY difficulties face the public officials who are responsi- 
•^-'-^■bleforthe construction, improvement and maintenance of the 
waterworks system of a community. Through long experience, the 
Pittsburgh-Des Moines Steel Company has developed a complete 
service to care for every phase of a municipal water- 
works installation. For more than thirty years we 
have been known throughout the United States and 
.experience Canada as manufacturers and erectors of elevated 
steel water tanks and standpipes, and also as con- 
tractors for complete waterworks systems. Our contracting service 
embraces every feature of municipal waterworks construction. 

A typical waterworks and filtration plant which we recently 
completed included the fabricating and erecting of two standard 
Complete Pittsbur gh- Des Moines elevated steel tanks, the 
Water- construction of a power house, the installation of 

works In- the P um P s and the building of a filter plant, including 
Stallation a c08L ^ atlon basin and rapid sand filters. Another 
plant included five 1,000,000-gallon steel standpipes, 
the installation of six miles of large size cast iron pipe with the neces- 
sary hydrants and valves and also four miles of 30-in. riveted steel 
force mains. Work in connection with the standpipes consisted 
of the excavation of 25,000 cubic yards of earth for the foundation 
site, and the construction of the concrete foundations themselves. 
We also installed the automatic electric control equipment for 
maintaining the proper level of water in the standpipes at all times. 
The Pittsburgh-Des Moines Steel Company is prepared to 
handle any waterworks installation from start to finish. We will 
From assist you in selecting the improvements contem- 

Start to plated, and our plans will be backed by our 

rinish experience in hundreds of communities, small ham-

Standpipes 
for Municipal Service 



I 



"F the storage tank can be located on a hill near the town, a steel 
standpipe will be quite as effective as an elevated tank. For 
fire protection in the average community, a minimum nozzle pres- 
sure of forty to fifty pounds is required, equivalent to a water pres- 
Natural SUrC ° f about one nundred fe et. It is therefore 

Elevation evident that a standpipe on a hill one hundred feet 

Available or more above the town wil1 meet this need Q uite 

as well as an elevated tank on a hundred foot tower. 
Standpipes are comparatively simple to manufacture and erect, 
and large quantities of water can be stored in them at a very low 
cost per gallon. To secure the greatest economy, however, stand- 
p pipes should be designed with the height not over 

■p. . twice the diameter. Avoid building standpipes of 

j sm all diameter and great height, because the pressure 

will fluctuate greatly and only that part of the water 
which is at the necessary elevation will be available for use. One 
objection to a high standpipe in cold climates is that it is impractical 
to use a roof on account of floating ice, and open top tanks are 
always .dangerous to the public health. There is also danger of 
failure caused by falling ice on a warm spring day when the level 
of the water is low. 

An elevated tank should always be used if considerable height 
is necessary. In general a standpipe is not as sanitary and will 
never do "just as weir' as an elevated tank. The only reasonable 
and economical plan is to erect the type of water reservoir which 
the local conditions demand. After your consulting engineer has 
designed the system, the Pittsburgh-Des Moines Steel Company 
Will take over the entire job of constructing your water supply. 
You will thus be assured of a carefully designed and properly built 
waterworks system, well fitted to the needs of your community.

Steel Tanks versus Wood or 
Concrete Tanks 

TN the early days of the gravity pressure water system the wood 
A tank and tower were widely used throughout this country. 
Lumber was cheap and of excellent quality. Wood tanks and towers 
were cheaper than similar structures of steel and little consideration 
Steel More was given to the appearance of the structure. With 
Eeonom- the increasing scarcity of good timber and advancing 
ical lumber costs, the price advantage of wood tanks and 

towers disappeared and their quality was greatly reduced. The 
construction of wood towers has practically been discontinued. At 
present the initial cost of a standard Pittsburgh -Des Moines steel 
water tank and tower, even of small capacity, is almost as low as 
that of a wooden structure of the same capacity and height, and for 
large structures steel is much cheaper. 

A Pittsburgh-Des Moines steel tank will last a life-time with 
practically no maintenance cost except for painting at three or four 
year intervals. On the other hand, the effective life of the best 
wood tank is seldom more than ten years, and constant inspection 
and repair are necessary during the whole period. Over a term of 
years the cost of a Pittsburgh-Des Moines steel water tank and 
tower is much less than that of a wood tank and wood tower, or a 
wood tank on a steel tower. 

A Pittsburgh-Des Moines elevated steel tank is fire -proof, leak- 
proof and rot-proof, while a wood tank and tower has none of these 
p. - qualities. Unless a wood tank is kept constantly 

r If f filled witn water ' i1: wi H develop leaks that can never 

Rot n f be entirely re P air ed. Even under ideal conditions, 
a wood tank soon begins to leak, wasting water, 
increasing pumping costs and making the tank unsightly in appear- 
ance. Dangerous icicles form on the sides of the tank in winter, 
and are a menace both to the structure itself and to human life. 
In many cases wood tanks have been known to burst their hoops,

causing great property damage and

waste of water, and a very unsightly 
appearance of the tank itself. As 
the process of freezing and thawing 
continues, particles of the concrete 
"flake off" until eventually small

the walls become too thin for safe- 
ty. Concrete tanks cannot, there- 
fore, be classed as permanent struc- 
tures for this service. APittsburgh-

the safe, permanent and econom- 
ical way to store any amount of 
water.

How to Build a Waterworks 

FN the development of every community the time comes when 
changing conditions awaken its citizens to the urgent need of 
a system of waterworks for fire protection and for industrial and 
domestic use. Usually the task of installing this new system or 
Exoert improving the existing system is entrusted to the 

Advice P ubli c officials of the community. Often enough, 

Necessary t * iese men > although efficient servants of the public 
in the routine of official duties, find that the task 
of improving the water supply presents many technical problems 
which, very naturally, they are not prepared to solve without expert 
assistance. 

In the average community there oftens exists some doubt as to 
whether a waterworks system can be financed. Until this question 
Prelim- 1S decided, the officials very properly hesitate to 

employ an engineer. Here is where the Pittsburgh- 
Des Moines Steel Company can first help you. One 
of our representatives will gladly consult with your officials without 
incurring any obligation whatever on your part. If desired, we 
will examine the local situation, advise the type of system best 
suited to your community, and submit an approximate estimate 
of its cost. This information can then be published in the local 
newspaper or mailed to each voter so that he may be fully ad- 
vised on the proposed improvements, and be able to act and vote 
intelligently on the proposition. 

When your community has definitely decided to construct a 
municipal waterworks system, the next step should be to engage an

are capable of doing this work for you. Attention should be given 
to the insurance requirements, to the state laws governing the 
approval of plans by the board of health, and to the raising of the 
necessary funds by voting and issuing bonds. Any experienced 
waterworks engineer can advise you upon these matters. 
While the surveys and plans are being made, the officials should 
arrange to provide the necessary funds. The usual plan for financ- 
ing the work is to vote and sell bonds. In doing 
this, great care should be taken to have all proceed- 
ings legal, in order that the bonds can be sold without 
difficulty or delay. If it is necessary to sell the bonds at or above 
par, it is important that the proper rate of interest be fixed. Our 
extensive experience in the municipal waterworks field enables us 
to give you valuable advice on this subject. Usually the bonds 
should be sold before contracts are made for the construction of 

the work, since the ordinary con- 
tractor or manufacturer will not 
begin work before the funds are 
definitely assured. But in order 
to speed up the completion of 
the plant or to overcome diffi- 
culties due to unfavorable bond 
market conditions, the Pitts- 
burgh -Des Moines Steel Com- 
pany is prepared to make con- 
tracts for the construction of 
waterworks systems on the basis 
of receiving the bonds as pay- 
ment. 

After the plans are com- 
pleted and the money is assur- 
ed, the next step is to receive 
public bids and award a con- 
tract for the construction of the 
plant. It is always best to

in this particular field. The Pittsburgh-Des Moines Steel Company 
has been engaged in waterworks contracting for more than thirty 
years and has built hundreds of plants in all parts of the United 
States and Canada. Its reputation for dependable and satisfactory 
service is shown by the steady increase in its waterworks business

Scope of the 
Pittsburgh -Des Moines Service 

TN addition to the service which this company renders in the 
■*■ municipal field, we construct highway bridges of structural steel 
or reinforced concrete. Our organization is well fTiVhwav 
adapted to handle this work. Three great steel "Bridges 

fabricating plants, a staff of competent construction 
engineers and well-organized field crews combine to render prompt, 
efficient and economical service in this line of work. 

When deciding whether the proposed bridge shall be built of 
steel or of reinforced concrete, a number of factors should be taken 
into consideration. Depending upon local conditions, and the size 
and type of the bridge, a concrete structure will Steel or 

sometimes be cheaper than one of steel, or vice versa. P ejnforced 
Our engineers will gladly submit estimates of both Concrete 
types of construction to help you settle this problem. Bridges 

There is also the question of beauty against that

Simplification and Standardization 
in Production 

THE World War taught America the necessity of eliminating 
waste and conserving labor and material in industry. Unprec- 
edented demands were made upon our industries in order to feed 
and clothe the allied armies and supply munitions. Production in 
m . __ r t i every line was speeded up to an unheard-of pace and 

The World , . „ . e . u 

contributed in large part to the winning of the war. 

Wot' 

In the effort to hasten output and eliminate waste, 

VT - the idea of standardization received great impetus. 
the Need 

Both products and methods of manufacture were 

analyzed and simplified to insure maximum production. 

A marked instance of the success achieved through standard- 
ization was the ship building industry. A few, simplified designs 
were used, all parts were interchangeable, and each 
Standard- part was ma & e by the factory best equipped to pro- 
ized Ships duce that art i c i e . i n the shipyards the equipment 
was assembled under standardized methods and new 
ships launched at a rate previously unknown. Similar methods 
prevailed in the manufacture of munitions and other supplies needed 
by our armies. 

Following the war, the United States Department of Commerce 
under the direction of Secretary Hoover launched a campaign to 
carry this war-time lesson to peace-time production. Extensive 
Deoart- investigations were made of conditions existing in 

t r various important industries. Manufacturers then 
P met in conference and decided upon the designs most 

r* > essential to their field. In the paving brick industry, 

Campaign 

sixty-six sizes of brick were studied and discussed, 
and this number reduced to six. A great saving in cost both to 
the manufacturer and the consumer was thus achieved by the elimi- 
nation of unusual or unessential designs. The automotive industry 
is perhaps the outstanding leader in standardized manufacture, 
and prices in this field reflect the savings made. 



P I T T S B U R G H - I) E S MOINES STEEL COMPANY 



Standardization of a product does three important things. It 
assures a high grade article because finer design and workmanship 
can be developed in a more limited field. It reduces the cost of the 
product, because of the greater efficiency of the labor Benefits 
involved and the saving in the cost of basic material ; Secured 

both the manufacturer and the consumer benefit by 
this economy. It speeds up delivery, because the manufacturer can 
carry a complete stock of both raw materials and finished products. 
Incidentally it makes it easy to order any desired article, saving 
time and trouble for the purchaser. 

Continuous production can be maintained by producing for 
stock during slack seasons. This assures steady employment to 
the workers, and benefits the country as a whole. Thus, labor, 
the manufacturer, and the consumer all share in the results secured 
by standardization. 

The Pittsburgh-Des Moines Steel Company did not wait for 
general action to be taken on the question of steel tank standard- 
ization. More than a year before the Department Standard 
of Commerce called for a conference, we had stand- Water 

ardized our products. We carry a stock of these Towers 

tanks and towers which are most generally used, 
completely fabricated, and ready for shipment. A table of our 
standardized designs appears on page 39. 

Naturally, in the field of Municipal Waterworks, there is always 
a demand for towers and tanks of special design to meet unusual 
conditions. We are always ready to quote on work of this kind, 
and the quality of our special tanks is as reliable as that of our 
standard designs.

Useful Information 

One cubic foot of fresh water 62 degrees F. weighs 62.36 pounds. 
One United States gallon of fresh water weighs 8.33 pounds. 
One cubic foot is equivalent to 7.48 U. S. gallons. 
One U. S. gallon contains 231 cubic inches. 

2.31 feet depth of fresh water will produce a pressure of one 
pound per square inch, therefore to find the pressure per square inch 
of a column of water, divide its height in feet by 2.31 or multiply by 
.433. 

To compute the horse power required to elevate water to a given 
height, multiply the number of gallons raised per minute by 8.33 and 
by the total vertical height in feet between the surface of water in 
well and surface of water in standpipes or reservoir, and divide 
the product by 33000. Add from 60 per cent to 100 per cent for 
friction and other losses in determining size of engine.

History of the 

Pittsburgh-Des Moines Steel 

Gompany 

THE business now being carried on by the Pittsburgh D 
Moines Steel Company, began as a partnershi] 

W. H. Jackson and B. N. Moss in 189.S under the firm n 
Jackson & Moss, Engineers and Contractors This fir 
headquarters at Des Moines, Iowa and specialized in the building 

of waterworks plants. Mr. Jackson had pn been C 

Engineer of Fort Madison, Iowa and Mr. Moss had been ei 
on construction work in Chic 

In 1899, E. W. Crellin, who had for several en engau 

in contracting for waterworks plants and general 
in Iowa and adjoining si irted the erection of a bridge I 

at Des Moines, Iowa. 

In March 1900, the firm of Jackson & Moss and Mr Crellin 
joined in the organization of the Des Moines Bridge and Iron V. 
The new company continued the waterworks contracting of tl 
firm and also added the fabrication and erection of bridge 
structures. This Company has had a very large share in the- build 
ing of the Central West. More than a third of the wateru 
terns of Iowa have been built wholly or in part by this organ: 

At the time Jackson & Moss entered the waterworks held, th 
were very few steel structures used for the storage of water. The 
larger cities used earth or masonry reservoirs and the small towns 
stored water in wooden tanks, elevated upon wooden water towe: 
Jackson & Moss introduced the substitution of economically de- 
signed steel towers for the old style wooden towers and secured a 
patent upon this style of construction in 1896. They were among 
the earliest builders of hemispherical bottom steel tanks for the 
storage of water. 

Within a few years the Des Moines Bridge and Iron Works 



PITTSBURGH-DE> MOINES - T E E L COMPANY 



were building elevated steel tanks in practically every state n the 
Union. This made it desirable to have an eastern factory and in 
1907 a plant was started at Pittsburgh, Pennsylvania. The branch 
soon outgrew the home business and Mr. Crellin and Mr. Jackson 
moved to Pittsburgh. The name of the business was then changed 
to the Pittsburgh-Des Moines Steel Company. 

The Company's activities have steadily expanded and now 
include many additional lines beside bridge and tower construction 
Prominent among these is the construction of radio towers. Mes 
sages may be sent around the world using the radio towers built 
by this Company at Porto Rico, New Orleans, Great Lakes, Marc 
Island, Guam, Manilla, and Bordeaux, France. The last named 
station is known as the La Fayette Radio Station and consist 
8 self supporting steel towers 820 feet high. This was built for 
the United States government during the war and is recognized 
as the largest of its kind in the world. 

The company's other activities during the war embraced flu 
construction of the waterworks features of the cantonment at Cam]) 
Dodge, the furnishing of a large numbei of government w 
towers two of which were In m Fort Oglethorpe within 

28 days from the date of i and the furnishing of thouse
